Roestvast staal is in principe een Fe-Cr legering met voldoende Cr om he t materiaal tegen corrosie en oxidatie te beschermen door de vorming van een dunne en stabiele laag chroomoxide aan het oppervlak. Naast een uit stekende corrosie- en oxidatieweerstand in vergelijking met koolstofstaa l, biedt roestvast staal een combinatie van goede mechanische thermische en chemische eigenschappen voor een relatief lage kostprijs. Voor hoge- ...

In this study, modified 12% Cr stainless steel with very low carbon level (0.01%) to improve the weldability and mechanical properties, still conforming to EN 1.4003 and UNS S41003 grades, was joined by gas metal arc welding. Plates 12 mm thick were welded with ER309LSi, ER308LSi, and ER316LSi austenitic stainless steel consumables. Several samples extracted from the joints were subjected to mechanical testing by means of tensile, bend, and ...

Modified X2CrNi12 stainless steel, conforming to EN1.4003 and UNS S41003 grades, has been designed with less carbon (<0.015%) and impurities to improve the weldability and mechanical properties. The present paper deals with submerged arc welding (SAW) of 30 mm thick plates of this steel with austenitic and duplex stainless steel consumables. Several samples extracted from the welded joints were subjected to mechanical testing by means of ...

The inclusions and precipitates in Ti-Nb stabilized ultra-pure ferritic stainless steel were extracted without any damage by an electrolytic method in a non-aqueous solution. Field emission scanning electron microscope and energy dispersion spectrum were used to characterize morphology and composition of the inclusions. The results showed that most inclusions in higher Ti bearing ferritic stainless steel were Ti(C, N) in cubic structure or TiOx ...

An experimental and numerical study of ferritic stainless steel tubular cross sections under combined loading is presented in this paper. Two square hollow section (SHS) sizes—SHS 40×40×240×40×2 and SHS 50×50×250×50×2 made of Grade EN 1.4509 (AISI 441) stainless steel—were considered in the experimental program, which included 2 concentrically loaded stub column tests, 2 four-point bending tests, and 14 eccentrically loaded stub column tests. In ...

Steel-concrete composite floors are commonly used in construction due to their favourable weight-to-depth ratio and erection time. Typically, concrete is poured onto a galvanised steel deck acting as formwork. However in case of floors exposed to corrosive environments, stainless steel is likely to be chosen over galvanised steel. Besides its better corrosion resistance, stainless steel also offers desirable aesthetic appearance and good ...

This paper presents the performance of EN 1.4003 ferritic stainless steel hollow section columns when exposed to fire loading. Experimental analysis of the behaviour of ferritic stainless steel structural members in fire represents a novelty. In detail, three column tests were carried out in the framework of the Research Fund of Coal and Steel (RFCS) project named Structural Applications of Ferritic Stainless Steels (SAFSS, RFSR-CT-2010-00026). ...

© 2015 Taylor & Francis Group, London. This paper presents a comprehensive experimental study of ferritic stainless steel tubular crosssections under combined loading.Two square hollowsection (SHS) sizes – SHS 40×40×2 and SHS 50×50×2 in grade EN 1.4509 stainless steel were considered. In total, two concentric compression tests, ten uniaxial bending plus compression tests and four biaxial bending plus compression tests were carried out. The ...
